Capt. Jenn Jackson with the Royal Canadian Air Force would not say where the plane was heading from, citing the sensitive nature of the case.

Jackson said rescue crews longlined from Air Force helicopters to hoist the survivors for transfer to hospital.

“No challenges have been reported,” she said. “I know that we had five search and rescue technicians jump in to assist the casualties on the ground and assess the rescue scene.”

Because of the remote area of the crash, no pictures are yet available from the scene.

B.C. Emergency Health Services (BCEHS) said two of the patients are in critical condition, while the other three are in serious but stable condition.

All five patients have been taken to hospital in Port Hardy by Canadian Coast Guard crews, BCEHS confirmed, where they landed around 7:30 p.m. and have been assessed.

The two patients in critical condition are being flown to hospital in Vancouver.

“Our thoughts are with those involved in the crash and their loved ones and are devastated by this fatal accident,” the statement reads.

B.C. Premier John Horgan also posted his condolences “with those affected by this tragic accident” on social media.
